(HF/ ffff BY I ATTORNEYs United States Patent 3,184,228 MILLING MACHHWE VISES AND THE LIKE AND AUXHJARY JAWS THEREFOR Edmond Z. Chenette, Scribner Ave, Norwallr, Coma, and Leo E. Chenette, Clearwater, Fla. Filed Oct. 26, 1962, Ser. No. 233,243 6 Claims. ((1 269-234) This invention relates to vises for milling machines and the like and the invention has particular reference to auxiliary jaws therefor having relative movement toward closed relation by camming action.

The invention comprehends auxiliary jaw adapted for clamping articles above the plane of the vise so as to increase the usefulness thereof.

An object of the invention is to provide an auxiliary jaw member having relatively movable jaw parts engaged by a cam which is moved by the movable jaw of the vise for varying the spacing of the relatively movable jaw parts.

The usual milling machine vise and the like have fixed and movable jaws which do not provide much depth for holding articles therebetween whereby the vise is thereby limited to its usefulness. The present invention overcomes the limitations and disadvantages of the usual type of milling machine vise and the like by providing an upstanding auxiliary jaw member which is releasably secured to the fixed jaw of the vise and which is provided with a laterally extending fixed jaw and a movable jaw member adapted to be moved into clamping relation with an article by a wedging member which is moved to cam the movable member upwardly by the movement of the movable member of the vise.

Another object of the invention is to provide an auxiliary jaw member which is adjustable from upright relation with reference to the vise to an angular relation therewith.

Still another object of the invention is to provide an auxiliary jaw member which may be conveniently fixed to and removed from the fixed jaw vise.

The invention includes an auxiliary jaw member which is releasably secured to the fixed jaw of a vise and which extends upwardly therefrom providing a jaw face disposed substantially in parallel relation with the transverse plane of the vise and with one or more movable shims disposed therebelow and supported by a camrning member for camming the shims toward the transversely laterally extending jaw face by movement of the movable jaw of the vise.

With the foregoing and other objects in view, reference is now made to the following specifications and accompanying drawings in which the preferred embodiments of the invention are illustrated.

In the drawings:

FIG. 1 is a plan of a milling machine vise having an auxiliary jaw member constructed in accordance with the invention.

FIG. 2 is a side view of the auxiliary jaw member and wedging member with the vise shown in section taken approximately on line 22 of FIG. 1.

FIG. 3 is a fragmentary view in side elevation showing a portion of the vise and a modified form of auxiliary jaw member constructed in accordance with the inven tion.

FIG. 4 is a sectional view taken approximately on line 4-4 of FIG. 3.

FIG. 5 is a fragmentary plan view of the base taken on line 55 of FIG. 3 with the auxiliary jaw member removed.

FIG. 6 is a plan view of the auxiliary jaw member taken on line 6-6 of HG. 3.

Referring to the drawings and more particularly to the form of the invention illustrated in FIGS. 1 and 2 thereof, an upwardly extending member constituting an auxiliary jaw member 10 is provided which is adapted to be releasably secured to the fixed jaw 11 of a vise V of the type used in conjunction with milling machines and the like.

The vise V includes a base 13 having recesses 14 at the ends thereof for receiving bolts adapted for attaching the vise to the table of a milling machine and the like. The base is also provided with an under-cut slot 15 extending longitudinally of the upper face thereof in which is slidably received a corresponding shaped tongue 16 depending from the underside of the movable jaw 17 of the vise for guided movement of the movable jaw toward and away from the fixed jaw 11. The movable jaw 17 is moved by the turning of a screw 18 swivelly mounted in a sleeve 1? secured in the upstanding flange 21 of the base with the inner end of the screw 18 threadedly engaging the threaded bore 22 extending longitudinally of the movable jaw 17. The screw is adapted to be turned by a handle member (not shown) engaging the outer end 23 thereof and is swivelly mounted in the sleeve 19 for rotation in either direction to permit of movement of the movable jaw 17 toward and away from the fixed jaw 11. The base 13 includes two top plates 20 and 20' which are secured thereto by screws 24 and are spaced apart longitudinally to form the slot 15 therebetween.

The auxiliary jaw member 10 is generally of U-shaped formation in vertical section including an inwardly directed head 25 at its upper end and an inwardly directed foot 26 at the lower end thereof. The jaw member 10 is mounted on the plates 20 and 20 of the base 13 of the vise and snugly fits a recess 27 extending transversely thereof adjacent the fixed jaw 11. The auxiliary jaw member 10 is affixed to the forward face of the fixed jaw 11 by a headed pin 23 and one or more screws 29 having their inner ends engaging in openings 34) and 31 in the auxiliary jaw member. The inwardly directed head 25 provides a jaw face 32 on the underside thereof which extends laterally of the vise and is disposed in spaced relation above the foot 26 and in substantially parallel relation with the plane of the vise. The inwardl directed foot 26 is formed with a rearwardly inclined cam face 33 which is located below the jaw face 32.

A cam follower or wedging member 34 is disposed between the movable jaw 17 and the foot 26 of the auxiliary jaw member if? and is formed with a face 35 complementary to the cam face 33 and which is arranged in camming engagement therewith. One or more blocks or Shims 36 are mounted upon the wedging member which are moved upwardly toward the jaw face 32 by the upward camming of the wedging member on the inclined face 33 with the movement of the movable jaw 17 toward the fixed jaw 11. The shims may be of any desired number and as illustrated in FIG. 2 of the drawings, two such shims are provided for gripping articles between the uppermost shim and the jaw face 32.

Construction in this manner the head 25 forms the fixed auxiliary jaw and the uppermost shim or block 36 forms the movable auxiliary jaw which provide means for holding an article in position for milling, facing, drilling and other work thereon which may be too large for holding in the usual vise.

Instead of the auxiliary jaw member 16 which is adapted to be secured in upright relation on the base, an auxiliary jaw member 40 may be provided which is adapted to be disposed in acute angular relation with the longitudinal plane of the base as illustrated in FIGS. 3 and 4 of the drawings. In this form of the invention the auxiliary jaw member 44 is adjustably connected with a foot 41 which is recessed to receive the reduced portion 42 of the jaw and'with' a bolt 43 extending throughaligned openings in the foot and jaw member for securing the jaw-member in} adjusted set position with refer- V ence .to the base.- The foot 41" is-mounted on the upper. face of the plates '20 and 20'-of-the base 13 of .the vise- V V and snugly fits the recess 27 therein adjacent the fixed jaw 1'1 asin the previous form of the invention. The foot 41',

for camming said shimnpwardly with the movement of 'the movable jaw of the vise toward the fixed jaw thereof for holding articlesv between said head and shim.

face of the fixed jaw 11.

'Theauxiliary jaw membert40 is provided with ahead 2 44 having a jaw face 45 on the under side thereof and blocks or shims 46 are provided as in theprevious form of the invention which are, slidable .on the auxiliary jaw member 40 towards and away from the jawface 45. A

the jaw to the deisredtangular relation. In order to earn the blocks 46 upwardly for the various angular positions" different sizes of rollers 47 t and blocks 48 may be employed and when in the desired angular position the bolt 43 is tightened for securing the jaw in set relation. 7 It will be understood that the head 44 forms the fixed auxiliary jaw while the uppermost 'shim or block 46 forms themovable-auxiliary jaw. The shoulder 51- of the bolt 43 bears against an annulus 52 whereby tightening of the bolt tightens the reduced portion 42 of the jaw member. 40 against one side of the foot 41'; to thereby hold the jaw members inta desired set position. The dial 50 on the side face of the foot.41 serves as a guide for manually set ting the jaw member 40 at any point between the vertical 1 and angle of 45 degrees.
